Welcome to Docker for Mac!
（欢迎使用MAC版本的Docker）
Docker is a full development platform for creating containerized apps, and Docker for Mac is the best way to get started with Docker on a Mac.
（Docker是一个创建容器式APP的完整开发平台，并且Docker For Mac是在Mac上使用Docker的最佳方式）
Stable channel
This installer is fully baked and tested, and comes with the latest GA version of Docker Engine. This is the best channel to use if you want a reliable platform to work with. These releases follow a version schedule with a longer lead time than the betas, synched with Docker Engine releases and hotfixes.On the stable channel, you can select whether to send usage statistics and other data.
（稳定版本是经过完全测试过的，并且使用Docker Engine的最新的GA版本。如果你想要一个可靠的开发平台，这是最好的版本。这些版本遵循着比betas更长交付时间的版本计划，并且与Docker Engine的修补程序同步进行。在稳定版本中，你可以选择是否发送可用的统计信息和其他数据）
System Requirements: Docker for Mac will launch only if all of these requirements are met.
（系统要求：仅当满足所有这些要求时，Mac版Docker才会启动。）
Mac must be a 2010 or newer model, with Intel’s hardware support for memory management unit (MMU) virtualization; i.e., Extended Page Tables (EPT) and Unrestricted Mode.
（Mac必须是2010或更新的型号，具有英特尔对内存管理单元（MMU）虚拟化的硬件支持; 即扩展页表（EPT）和非限制模式。）
OS X El Capitan 10.11 and newer macOS releases are supported. At a minimum, Docker for Mac requires macOS Yosemite 10.10.3 or newer, with the caveat that going forward 10.10.x is a use-at-your-own risk proposition.
（支持OS X El Capitan 10.11和更新的MacOS版本。 至少Docker for Mac需要使用macOS Yosemite 10.10.3或更新版本，注意10.10.x之前的版本则自担风险。）
Starting with Docker for Mac stable release 1.13 (upcoming), and concurrent Beta releases, we will no longer address issues specific to OS X Yosemite 10.10. In future releases, Docker for Mac could stop working on OS X Yosemite 10.10 due to the deprecated status of this OS X version. We recommend upgrading to the latest version of macOS.
（从Docker for Mac稳定版1.13（即将推出）和并发的Beta版本开始，我们将不再解决OS X Yosemite 10.10特有的问题。 在将来的版本中，由于OS X版本的弃用状态，Docker for Mac可能会停止在OS X Yosemite 10.10上运行。 我们建议升级到最新版本的macOS。）
At least 4GB of RAM
（至少4GB的RAM）
VirtualBox prior to version 4.3.30 must NOT be installed (it is incompatible with Docker for Mac)
（不能安装版本4.3.30之前的VirtualBox（它与Mac的Docker不兼容））
You will be asked to authorize Docker.app
with your system password during the install process. Privileged access is needed to install networking components and links to the Docker apps.
（你会被要求授权Docker.app在安装的过程中使用系统密码，安装网络组件和Docker.apps的关联需要特权访问）
Double-click Docker.app
to start Docker.
（双击<code>Docker.app</code>来启动Docker）
Docker app in Hockeyapp
The whale in the top status bar indicates that Docker is running, and accessible from a terminal.
（在顶层bar条的鲸鱼图标表明Docker正在运行中，并且可以从terminal中访问）
Whale in menu bar
If you just installed the app, you also get a success message with suggested next steps and a link to this documentation. Click the whale ( ) in the status bar to dismiss this popup.
Docker success
（如果你刚安装应用，你会获得一条成功消息，它包含了建议后续的步骤和文档的链接，双击状态栏中的鲸鱼图标来关闭此弹出信息） Click the whale (
) to get Preferences, and other options.
Docker context menu
（单击鲸鱼图标获得首选项和其他选项。）
Select About Docker to verify that you have the latest version.
Congratulations! You are up and running with Docker for Mac.
（选择 About Docker 以验证您是否具有最新版本。
恭喜！ 你使用Docker for Mac运行。）
Note: The above is an example. Your output will differ if you are running different (e.g., newer) versions.
（提示：上面只是个例子，如果你运行不同（例如更新）的版本，你的输出会不同）
Step 3. Explore the application and run examples
1.Open a command-line terminal, and run some Docker commands to verify that Docker is working as expected.
Some good commands to try are docker version
to check that you have the latest release installed, and docker ps
and docker run hello-world
to verify that Docker is running.
（步骤3.探索应用程序并运行实例：
1、打开命令行终端，并且运行一些Docker命令来验证Docker是否正常工作。
一些好的命令例如<code>docker version</code>检查是否为最新版本，并且<code>docker ps</code>和<code>docker run hello-world</code>来验证Docker正在运行）
2.For something more adventurous, start a Dockerized web server.
docker run -d -p 80:80 --name webserver nginx
（2、更进一步则是使用<code>docker run -d -p 80:80 --name webserver nginx</code>启动Dockerized Web服务器）
<pre>docker run -d -p 80:80 --name webserver nginx</pre>
Note: Early beta releases used docker
as the hostname to build the URL. Now, ports are exposed on the private IP addresses of the VM and forwarded to localhost
with no other host name set. See also, for Beta 9.
（提示：早期的测试版本使用<code>docker</code>来作为主机名构建URL，现在，端口会暴露在VM的私有IP地址上，并且转发到<code>localhost</code>而不需要设置其他主机名，详情参阅 ）
Run docker ps while your web server is running to see details on the webserver container.
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 56f433965490 nginx "nginx -g 'daemon off" About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 443/tcp webserver
（当你的web服务器正在运行时，运行<code>docker ps</code>来查看webserver容器的详情）
<pre>
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
56f433965490 nginx "nginx -g 'daemon off" About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 443/tcp webserver
</pre>
Stop or remove containers and images.
（停止或移除容器和镜像）
The <code>nginx</code> webserver will continue to run in the container on that port until you stop and/or remove the container. If you want to stop the webserver, type: <code>docker stop webserver</code> and start it again with <code>docker start webserver</code>. A stopped container will not show up with <code>docker ps</code>; for that, you need to run <code>docker ps -a</code>
（除非你终止或移除容器，否则<code>nginx</code>服务器会继续在那个端口的容器上运行。如果你想终止服务器，输入<code>docker stop webserver</code>并使用<code>docker start webserver</code>重启，一个已终止运行的容器中运行<code>docker ps</code>不会有显示，因此你需要运行<code>docker ps -a</code>）
To stop and remove the running container with a single command, type: <code>docker rm -f webserver</code>. This will remove the container, but not the <code>nginx</code> image. You can list local images with <code>docker images</code>. You might want to keep some images around so that you don’t have to pull them again from Docker Hub. To remove an image you no longer need, use <code>docker rmi</code> followed by an image ID or image name. For example, <code>docker rmi nginx</code>.
（为了停止并删除正在运行的容器，你需要键入一条命令 <code>docker rm -f webserver</code>，这可以移除容器，但不会移除<code>nginx</code>镜像，你可使用<code>docker images</code>列出本地镜像列表。你想要保留一些镜像，这样不必再从Docker Hub中拉取镜像。要删除你不再需要的镜像，请使用 <code>docker rmi</code>命令，后面参数为镜像的ID或镜像的名称。例如<code>docker rmi nginx</code>）
（从鲸鱼图标中的选项栏选择Preferences，你可以设置以下正在运行时选项 ）
General
Preferences
Auto-start, update, and backups
Docker for Mac is set to automatically start when you log in. Uncheck the login autostart option if you don’t want Docker to start when you open your session.
（Auto-start, update, and backups：
Docker for Mac设置为在您登录时自动启动。如果您不希望在打开session时启动Docker，请取消选中login autostart选项。）
Docker for Mac is set to check for updates automatically and notify you when an update is available. If an update is found, click OK to accept and install it (or cancel to keep the current version). If you disable the check for updates, you can still find out about updates manually by choosing
->Check for Updates（Docker for Mac设置为自动检查更新，并在更新可用时通知您。 如果找到更新，单击OK接受并安装它（或取消保留当前版本）。 如果禁用检查更新，您仍然可以通过选择 - >Check for Updates）
CPUs
By default, Docker for Mac is set to use 2 processors. You can increase processing power for the app by setting this to a higher number, or lower it to have Docker for Mac use fewer computing resources.
（CPU：默认情况下，Docker for Mac设置为使用2个进程。 您可以通过将应用程序设置为更高的数字来提高应用程序的处理能力，或者降低它使Docker for Mac使用更少的计算资源。）
Memory
By default, Docker for Mac is set to use 2
GB runtime memory, allocated from the total available memory on your Mac. You can increase the RAM on the app to get faster performance by setting this number higher (for example to 3) or lower (to 1) if you want Docker for Mac to use less memory.
（内存：默认情况下，Docker for Mac设置为使用2 GB运行时内存，从Mac上的总可用内存中分配。 您可以增加应用程序的RAM以获得更快的性能，或者如果你希望Docker for Mac使用更少的内存，通过设置这个数字更高（例如到3）或更低（到1）。）
